| 摘 要： | 为探讨多效唑对大丽花生理特性的影响，以高生品种‘陇上雄鹰’盆栽扦插苗为试验材料，株高30 cm时，用不同浓度的多效唑对大丽花进行一次喷施处理，研究了大丽花叶片内生理生化指标的变化。在多效唑处理条件下，‘陇上雄鹰’叶片内叶绿素、可溶性糖、可溶性蛋白和脯氨酸含量较对照均显著增加，SOD、POD和CAT活性也明显提高，丙二醛含量减少；且随着施用浓度的增加，作用效果增强。其中以125 mg/L多效唑处理效果最显著，叶绿素、可溶性糖、可溶性蛋白和脯氨酸含量分别较对照增加0.75 mg/g、17.90 mg/g、22.13 μg/g和29.92 μg/g；SOD、POD和CAT活性较对照提高1.97、1.75和1.80倍，丙二醛含量减少30.70%。说明喷施多效唑可显著影响大丽花生理特性，提高可溶性固形物含量及抗氧化物酶活性，促进发育，增强抗逆性。 |

| Abstract: | With ＇Longshangxiongying＇ as experimental material, effects of different concentration of PP333 on the physiology characteristics in Dahlia pinnata leaves were studied. The Dahlia pinnata was treated with PP333 when the plant height was 30 cm and the physiology characteristics were tested. The results showed that PP333 increased the content of chlorophyll, soluble sugar, soluble protein, proline, decreased the level of MDA, and improve the activity of antioxidant enzymes in Dahlla pinnata leaves. In addition, the effects were better with the increase of concentration. The treatment of 125 mg/L of PP333 had the significant positive effects. Compared with the CK, the content of chlorophyll, soluble sugar, soluble protein, proline were increased 0.75 mg/g, 17.90 mg/g, 22.13 μg/g and 29.92 μg/g, SOD, POD and CAT were improved 1.97, 1.75 and 1.80 times, MDA was decreased 30.70%. The result of study indicated that PP33J could significantly affect the physiological indexes of ＇ Longshangxiongying＇, improve the content of soluble solids and activity of antioxidant enzymes, promote the growth and development and enhance the resistance. |
